Subject: [PATCH] src/cplat.h: Don't define __USE_GNU

There were two things wrong with it:
- __USE_GNU is glibc-internal, the external define is _GNU_SOURCE
- defining such macros after the first include is wrong, in this case
it caused FTBFS on ia64.

An option would be to pass -D_GNU_SOURCE when building, but as far
as I can see the define was not (anymore?) needed at all.
